B — Sodium ethoxide
When ethanol reacts with sodium metal: $2\text{Na} + 2\text{CH}_3\text{CH}_2\text{OH} \rightarrow 2\text{CH}_3\text{CH}_2\text{O}^-\text{Na}^+ + \text{H}_2$. The other product is sodium ethoxide.

The reaction of ethanol with sodium is a standard 1-mark fact. Examiners expect you to recall the chemical equation and name the ionic product — sodium ethoxide ($\text{CH}_3\text{CH}_2\text{O}^-\text{Na}^+$). Do not confuse it with sodium hydroxide (which forms when sodium reacts with water, not ethanol).
